# beamcache: Erlang BEAM Cache

## Usage

```erlang

CacheName = my_cache,

Cache = #{a => 1, b => true, <<"key">> => "TEST"},

{module, CacheName} = beamcache:init(CacheName, Cache),

Cache = CacheName:get(),

true = CacheName:get(b),

false = CacheName:get(c, false).

```

To shut up xref and dialyzer add such module to sources:

```erlang

-module(testbc).

-export([get/0, get/1, get/2]).

get() -> erlang:nif_error(undef).

get(_) -> erlang:nif_error(undef).

get(_, _) -> erlang:nif_error(undef).

erase(_) -> erlang:nif_error(undef).

put(_, _) -> erlang:nif_error(undef).

```

To protect against using uninitialized cache add such module to sources:

```erlang

-module(testbc).

-export(['$handle_undefined_function'/2]).

'$handle_undefined_function'(F, A) ->

    {module, ?MODULE} = beamcache:init(?MODULE, #{a => 1, b => true, <<"key">> => "TEST"}),

    apply(?MODULE, F, A).

```

Or come up with a combination of the above examples...
